My coworker needs HALP! 2JZ Lexus

Hey Oppo, a coworker is thinking about trading his Dodge project truck for this. The car isn't currently running, the owner says the Apexi SAFC controller got reset to stock settings (his daughter did it on accident). My coworker called the shop that dynotuned this and they don't have any records on what was done.

The work was done in Chicago, do you guys think the aftermarket settings could still be on the device? If no, is there anyone here in (west) Michigan you guys know of that could redo this, how much would it cost? The owner says it currently starts up but is running too rich and immediately dies.

One of my concerns is also that other things could be wrong, that you won't know about until you get it tuned correctly. Do you guys know what he should be asking? What he should be looking at?

Before someone does this:

How?!

Kinja'd!!!

Sounds like someone else's failed project. I don't know anyone with a tuned project car that hasn't had a lot of problems. And those were their projects. This is someone else's!

This sounds a little fishy as the car shouldn't need the SAFC just to idle but there may be air/fuel changes that are affecting it. In any case here are the base settings for the SAFC for the GS and with these the car should run.

-Go to [main]
~>[setting] ~> [3. TH-Point] ~>
[Lo-94, Hi-95]

-Go to [main] ~>[etc.]
~> [1. Sensor Type] ~> [1.
Hot-Wire] ~> [in-12, Out-12] ~> [in-1, Out-1]

-Go to [main] ~>[etc.]
~> [2. Car Select] ~> [Cyl:6, Thr: UP]

-Go to [main] ~>[etc.]
~> [3. Graph scale] ~> [Ne = 7000rpm]

[Ne-POINT = 3500, 4000,
4500, 5000, 5500, 6000, 6500, 7000]

[Dec. -Air = NOT USED, unless you
want to use it to compensate for venting your BOV to atmosphere]

Do not modify the low throttle settings. While at low throttle (in closed loop mode) the ECU will counteract any changes made and over time your long term fuel map will be modified. I recommend modifying your high throttle fuel curve on the dyno with an air/fuel ratio meter & egt gauge installed. For maximum power, one probably wants to run an air to fuel ratio of between 11:1 (rich) and 12.5:1 (lean) Do yourself a favor and pay a professional to tune it. If you lean your engine out, things can melt.

Sounds super fishy! A big headache if you ask me. Unless he's into that sort of thing

She was trying to adjust the NOS spray to keep from blowing the welds on the intake.

She was in the car doing homework and listening to music and thought the tuner was an equalizer.

This reeks of the dog ate my paper, kind of story.

Wow, thanks!

So you think if it's set to this the car should at the very least be able to idle correctly?

Girls. Then again, I can't blame them; it just serves as a new reason to turn the passenger airbag into a hidden compartment.

Wow, so many horrid memories bubbling up...Never thought I would ever have to look at this list of instructions again after ripping one out of my car and the clusterfuck of HKS VPC/GCC shit that came with it.

Look a that shit Bozi T posted thats about as clear as the menu screens are! Press one goddamn button on those things without being an SAFC master it will fuck itself and your life all on its own.

Easy for the layperson not well versed on tuning cars... from... the 90's... to mistake this for an audio controller.

My friend kicked in my SAFC and bent its head unit bezel by climbing in the back seat, pressed some buttons...never ran the same again and I didn't know what all the settings were from the dyno tune by the owner before me. They called it the squid after that because it would blast a diesel-like cloud of smoke briefly after flooring it.

I'm not seeing a price in here but I would make the very stable argument he needs to drop it at least $500 for the necessary dyno tune because there are plenty of long term injuries from not having a close to perfect a/f ratio.

Or you could by a wideband reader and do it yourself its unfortunate they weren't always as cheap or really necessary if you had a good Dyno shop close by.

On DSM forums the phrase " do you have wideband?? " is like the mission statement cuz we're all cheapskates...

Advice: If it's an A100/A108 project truck, then he shouldn't trade it, or if so, to one of us Opponauts.

What's an A100/108 project?

SpeedSix > Yowen - not necessarily not spaghetti and meatballs

You mentioned he had a Dodge project truck. If it's a Dodge A100/A108, he shouldn't trade it for sure.

Hmm, don't recall what year the truck is, it was really nice looking though, I think i would've rather kept hit, but his guy doesn't like holding on to cars for very long.

I can't stop him from doing this either, haha, he is doing the trade tomorrow.
